Tonga became a constitutional monarchy under King George Tupou I (named after King George III), in 1875. Stamps were first issued with a King George I visage in 1886. Tonga became a British Protectorate in 1900 under a Treaty of Friendship. Tonga, however, maintained its sovereignty, and the Tongan monarchy continues to this day.
